The invention discloses a cathode-anode interface modified layer film material of a solar cell and a preparation method of the cathode-anode interface modified layer film material. The cathode-anode interface modified layer film material is prepared from the following components in parts by mass: 3-6 parts of polyaniline, 2-5 parts of polyparaphenylenevinylene, 2-5 parts of WO3, 8-15 parts of 8- quinolinolato lithium, 2-8 parts of cesium carbonate, 0.18-0.76 parts of polystyrolsulfon acid, 0.3-1.6 parts of sodium dodecyl sulfate, 0.1-0.6 part of phosphite ester, 0.45-0.85 part of silicon carbide, 0.5-1.5 parts of molybdenum trioxide, 1-5 parts of carbon fiber powder, 1-5 parts of a thermal stabilizer and 3-10 parts of a ultraviolet light absorber. The interface modified layer film material is increased between the cathode and the anode of the solar cell, so that the current transformation between the cathode and anode interfaces can be improved, the loss of charge is reduced, and the photoelectric conversion efficiency of the solar cell is improved.
